The old filing cabinet at the back of the office has been largely untouched since Holwell employed the efforts of several interns to move to digital. Nevertheless, it remains one of the most comprehensive records of modern monsters, and is occasionally updated by some of the older Agents by means of backup, just in case.
Within are dozens of manilla folders, numbered from oldest to most recent Holwell-specific encounters.
